Polymorphism of CSN1S1 (g.12164G>A) and CSN2 (g.8913C>A) genes in pure and cross dairy goats

Casein genes directly control milk protein of animals. CSN1S1 (αS1-Casein) and CSN2 (β-Casein) influence on fractions. Genetic polymorphisms gene at g.12164G>A locus g.8913C>A were identified by PCR-RFLP technique. Animal samples pure dairy goats providing PE (5 hds.), Saanen (8 hds.) their crosses Sapera (50% Saanen, 50% PE) (51 SaanPE (75% 25% (3 from IRIAP goat station. Allele frequency, genotype heterozygosity value, Hardy-Weinberg (H-W) equilibrium value analyzed Popgen32 program. CSN1S1_g.12164G>A resulted in two alleles, i.e. G allele (192 bp, 145 101 bp) A (337 bp bp). The the highest frequenciest was successively (0.625), (0.578), (0.400), (0.333). Most heterozygote (Ho>He) H-W (q 2 count < q P0.05). Whereas CSN2_g.8913C>A monomorphic for possesing only C (233 162 bp), without (416 existent SNP could be a potencial molecular selection marker content goat.
